Puzzles tips

🧩

Choose a shift of 3 (the original Caesar shift) for classic puzzle design. Players who know history will try 3 first.

💡

For harder puzzles, use a shift that doesn't have an obvious mnemonic. Shift 7 or 17 are harder to guess than 1, 3, or 13.

🔍

Frequency analysis: in English, E is the most common letter. If you see lots of H in the ciphertext, the shift might be 3 (E+3=H).

🎯

For escape rooms, hide the shift number in a visual clue. A clock showing 7 o'clock is the key to a shift-7 cipher.
